使用SLRequest（无对话）将视频上传到ios 6中的Facebook的示例 [英] example of uploading video to facebook in ios 6 using SLRequest (without dialog)

问题描述

我正在寻找一个例子，其中使用iOS 6& SLRequest。我已经有我的代码可以上传照片。

提前感谢

解决方案

将视频分享到FB：

• 在developer.facebook.com上创建一个应用程序
$ b $在iOS平台上的app应用程序页面的develper.facebook.com中提到appName-info.plist中的AppId

• 提交应用程序BundleID

然后编码：

我们必须申请读权限，然后写权限。

   - （void）shareOnFB 
 {
 __block ACAccount * facebookAccount; 
 ACAccountStore * accountStore = [[ACAccountStore alloc] init]; 
 NSDictionary * emailReadPermisson = [[NSDictionary alloc] initWithObjectsAndKeys：
 FB_APP_ID，ACFacebookAppIdKey，
 @ [@email]，ACFacebookPermissionsKey，
 ACFacebookAudienceFriends，ACFacebookAudienceKey，
 nil ]。 
 
 NSDictionary * publishWritePermisson = [[NSDictionary alloc] initWithObjectsAndKeys：
 FB_APP_ID，ACFacebookAppIdKey，
 @ [@publish_stream]，ACFacebookPermissionsKey，
 ACFacebookAudienceFriends，ACFacebookAudienceKey，
 nil]; 
 
 ACAccountType * facebookAccountType = [accountStore 
 accountTypeWithAccountTypeIdentifier：ACAccountTypeIdentifierFacebook]; 
 //请求读取权限
 
 [accountStore requestAccessToAccountsWithType：facebookAccountType选项：emailReadPermisson完成：^（BOOL授予，NSError *错误）{
 
 if（授予） 
 {
 //请求写入权限
 [accountStore requestAccessToAccountsWithType：facebookAccountType选项：publishWritePermisson完成：^（BOOL授予，NSError *错误）{
 
 if（授予）
 {
 NSArray * accounts = [accountStore 
 accountsWithAccountType：facebookAccountType]; 
 facebookAccount = [accounts lastObject]; 
 NSLog（@访问Facebook帐户ok％@，facebookAccount.username）; 
 [self uploadWithFBAccount：facebookAccount]; 
} 
 else 
 {
 NSLog（@访问Facebook不被授予）; 
 //如果需要，额外的处理
 dispatch_async（dispatch_get_main_queue（），^ {
 //正常失败... 
 NSLog（@％@，error.description） ; 
 [self errorMethodFromFB：error]; 
}）; 
} 
}]; 
} 
 else 
 {
 [self errorMethodFromFB：error]; 
} 
}]; 
} 
  

然后从Facebook处理错误方法

   - （void）errorMethodFromFB :( NSError *）错误
 {
 
 NSLog（@访问Facebook不被授予 ）; 
 //如果需要，额外处理
 
 dispatch_async（dispatch_get_main_queue（），^ {
 
 //正常失败... 
 NSLog（@ ％@，error.description）; 
 
 if（[错误代码] == ACErrorAccountNotFound）
 [self throwAlertWithTitle：@错误消息：@找不到帐户请设置您的帐户在设置应用程序]; 
如果（[错误代码] == ACErrorAccessInfoInvalid）
 [self throwAlertWithTitle：@错误消息：@客户端的访问信息字典有不正确或缺失的值。 ]; 
 if（[error code] == ACErrorPermissionDenied）
 [self throwAlertWithTitle：@Errormessage：@操作未完成，因为用户拒绝了权限。]; 
 else 
 [self throwAlertWithTitle：@Errormessage：@Account access denied。]; 
}）; 
} 
  

然后消息警报

< （NSString *）标题消息：（NSString *）msg
{
[[UIAlertView alloc] initWithTitle：标题消息：msg委托：nil cancelButtonTitle：@OKotherButtonTitles：nil，nil] show];
}

处理上传方法

   - （void）uploadWithFBAccount：（ACAccount *）facebookAccount 
 {
 ACAccountCredential * fbCredential = [facebookAccount credential]; 
 NSString * accessToken = [fbCredential oauthToken]; 
 
 NSURL * videourl = [NSURL URLWithString：[NSString stringWithFormat：@https://graph.facebook.com/me/videos?access_token=%@，accessToken]]; 
 
 NSFileManager * fileManager = [NSFileManager defaultManager]; 
 
 NSArray * paths = NSSearchPathForDirectoriesInDomains（NSDocumentDirectory，NSUserDomainMask，YES）; 
 NSString * documentsDirectory = [paths objectAtIndex：0]; 
 NSString * foofile = [documentsDirectory stringByAppendingPathComponent：@me.mov]; 
 BOOL fileExists = [fileManager fileExistsAtPath：foofile]; 
 if（fileExists）
 {
 NSLog（@file saved）; 
} 
 NSString * filePath = foofile; 
 NSURL * pathURL = [[NSURL alloc] initFileURLWithPath：filePath isDirectory：NO]; 
 NSData * videoData = [NSData dataWithContentsOfFile：filePath]; 
 NSDictionary * params = @ {
 @title：@我傻，
 @description：@我用新的社交框架测试视频上传到Facebook。 
}; 
 
 SLRequest * uploadRequest = [SLRequest requestForServiceType：SLServiceTypeFacebook 
 requestMethod：SLRequestMethodPOST 
 URL：videourl 
参数：params]; 
 [uploadRequest addMultipartData：videoData 
 withName：@source
 type：@video / quicktime
 filename：[pathURL absoluteString]]; 
 
 uploadRequest.account = facebookAccount; 
 
 dispatch_async（dispatch_get_global_queue（DISPATCH_QUEUE_PRIORITY_DEFAULT，0），^（void）{
 [uploadRequest performRequestWithHandler：^（NSData * responseData，NSHTTPURLResponse * urlResponse，NSError * error）{
 NSDictionary * responseDictionary = [NSJSONSerialization JSONObjectWithData：responseData选项：NSJSONReadingMutableContainers错误：& error]; 
 NSString * responseString = [[NSString alloc] initWithData：responseData encoding：NSUTF8StringEncoding]; 
 
 if（error ）
 {
 NSLog（@Error％@，error.localizedDescription）; 
} 
 else 
 {
 [[[UIAlertView alloc] initWithTitle ：@恭喜！消息：@你的视频被自动发布到你的FB newsfeed委托：nil cancelButtonTitle：@OKotherButtonTitles：nil，nil] show]; 
 NSLog（@％@ responseString）; 
} 
}]; 
}）; 
} 
  

I am looking for an example where a video is posted to facebook using iOS 6 & SLRequest. I already have my code working for uploading a photo.

Thanks in advance!

解决方案

For sharing a Video to FB :

• Create an app on developer.facebook.com
• mention the AppId in appName-info.plist
• mention app BundleID in develper.facebook.com of your app page under iOS platform

Then on coding:

we have to request for read permission then write permission .

-(void)shareOnFB
{
      __block ACAccount * facebookAccount;
      ACAccountStore *accountStore = [[ACAccountStore alloc] init];
      NSDictionary *emailReadPermisson = [[NSDictionary alloc] initWithObjectsAndKeys:
                                    FB_APP_ID,ACFacebookAppIdKey,
                                    @[@"email"],ACFacebookPermissionsKey,
                                    ACFacebookAudienceFriends,ACFacebookAudienceKey,
                                    nil];

      NSDictionary *publishWritePermisson = [[NSDictionary alloc] initWithObjectsAndKeys:
                                       FB_APP_ID,ACFacebookAppIdKey,
                                       @[@"publish_stream"],ACFacebookPermissionsKey,
                                       ACFacebookAudienceFriends,ACFacebookAudienceKey,
                                       nil];

     ACAccountType *facebookAccountType = [accountStore
                                      accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
      //Request for Read permission

    [accountStore requestAccessToAccountsWithType:facebookAccountType options:emailReadPermisson completion:^(BOOL granted, NSError *error) {

    if (granted)
    {
        //Request for write permission
        [accountStore requestAccessToAccountsWithType:facebookAccountType options:publishWritePermisson completion:^(BOOL granted, NSError *error) {

        if (granted)
        {
             NSArray *accounts = [accountStore
                                     accountsWithAccountType:facebookAccountType];
             facebookAccount = [accounts lastObject];
             NSLog(@"access to facebook account ok %@", facebookAccount.username);
             [self uploadWithFBAccount:facebookAccount];
        } 
        else 
        {
             NSLog(@"access to facebook is not granted");
               // extra handling here if necesary
             dispatch_async(dispatch_get_main_queue(), ^{
                 // Fail gracefully...
                NSLog(@"%@",error.description);
                [self errorMethodFromFB:error];
                });
         }
      }];
    }
    else
    {
       [self errorMethodFromFB:error];
    }
  }];
}

Then Handle the error method from facebook

-(void)errorMethodFromFB:(NSError *)error
{

    NSLog(@"access to facebook is not granted");
   // extra handling here if necesary

  dispatch_async(dispatch_get_main_queue(), ^{

      // Fail gracefully...
      NSLog(@"%@",error.description);

      if([error code]== ACErrorAccountNotFound)
          [self throwAlertWithTitle:@"Error" message:@"Account not found. Please setup your account in settings app."];
      if ([error code] == ACErrorAccessInfoInvalid)
          [self throwAlertWithTitle:@"Error" message:@"The client's access info dictionary has incorrect or missing values."];
     if ([error code] ==  ACErrorPermissionDenied)
          [self throwAlertWithTitle:@"Error" message:@"The operation didn't complete because the user denied permission."];
     else
          [self throwAlertWithTitle:@"Error" message:@"Account access denied."];
  });
}

Then message alert

-(void)throwAlertWithTitle:(NSString *)title message:(NSString *)msg
{
     [[[UIAlertView alloc]initWithTitle:title message:msg delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil]show];
}

Handle Uploading method

-(void)uploadWithFBAccount:(ACAccount *)facebookAccount
{
    ACAccountCredential *fbCredential = [facebookAccount credential];
    NSString *accessToken = [fbCredential oauthToken];

    NSURL *videourl = [NSURL URLWithString:[NSString stringWithFormat:@"https://graph.facebook.com/me/videos?access_token=%@",accessToken]];

    NSFileManager *fileManager = [NSFileManager defaultManager];

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString* foofile = [documentsDirectory stringByAppendingPathComponent:@"me.mov"];
    BOOL fileExists = [fileManager fileExistsAtPath:foofile];
   if (fileExists) 
   {
       NSLog(@"file saved");
   }
   NSString *filePath = foofile;
   NSURL *pathURL = [[NSURL alloc]initFileURLWithPath:filePath isDirectory:NO];
   NSData *videoData = [NSData dataWithContentsOfFile:filePath];
   NSDictionary *params = @{
                         @"title": @"Me  silly",
                         @"description": @"Me testing the video upload to Facebook with the new Social Framework."
                         };

   SLRequest *uploadRequest = [SLRequest requestForServiceType:SLServiceTypeFacebook
                                              requestMethod:SLRequestMethodPOST
                                                        URL:videourl
                                                 parameters:params];
  [uploadRequest addMultipartData:videoData
                       withName:@"source"
                           type:@"video/quicktime"
                       filename:[pathURL absoluteString]];

    uploadRequest.account = facebookAccount;

    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void) {
        [uploadRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
            NSDictionary *responseDictionary = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableContainers error:&error];
            NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];

           if(error)
           {
                 NSLog(@"Error %@", error.localizedDescription);
           }
           else
           {
                [[[UIAlertView alloc]initWithTitle:@"Congratulations!" message:@"Your video is suucessfully posted to your FB newsfeed" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil]show];
                NSLog(@"%@", responseString);
           }
       }];
   });
}
